ok bob you went out for beer, thats not illegal you got assaulted probably over nothing, the persons who hit you are at fault, the fact you had been drinking has nothing to do with it unless you hit them first

you asked why the delay in symptoms well you may not have noticed them, we just try to get on with things others may have noticed changes but until your brain recovers to a point you can be unaware,

I won,t go into what happened to me but I too was assaulted and have 3 titanium plates in my head I was walking about at the hospital, but thought I was somewhere I was 3 days before, don,t know how long I was out for ether , I have been diagnosed with brain damage

the fact you have memory loss pre and post injury is significant

this has probably effected you on a few levels , but you are not alone, speak with your family if you can

headway UK have a help line and I can say they helped me, they have some good booklets to help you and your friends and family understand

you will and can get over this, you are young, I am the big 50 this year, try to keep in mind that we all have different levels of injury here,

this is a good safe place to vent talk and learn its also helps with keeping your brain active

keep off the booze, be kind to your self and rest and try to have some fun also
